[7] Barnbrook is also a type designer and has released typefaces including Bastard, Exocet, False Idol, Infidel, Moron, Newspeak, Olympukes, Sarcastic, Shock & Awe.

[1] From 1997 to 2003 Barnbrook collaborated with Young British Artist Damien Hirst, mainly on the design, layout and typography of his book I Want To Spend the Rest of My Life Everywhere, with Everyone, One to One, Always, Forever, Now,[10] and on artwork associated with his restaurant Pharmacy.

A recurring theme of Barnbrook's graphic design is the series of personal responses to political events, which often follow or develop detournement methods.

[3] He was a signatory to the First Things First 2000 manifesto, in which graphic designers pledged to "put their skills to worthwhile use'"and address the "unprecedented environmental, social and cultural crises" that they saw in the world.

[17] An exhibition of Barnbrook's work, entitled Friendly Fire, ran between June and October 2007 at the Design Museum in London.
